FritzZyme 9 is formulated with targeted strains of live nitrifying bacteria, designed to significantly lower fish mortality by combating harmful ammonia and nitrite levels in saltwater aquariums.

  • Usage Guidelines: For new setups, apply 4 oz (119 ml / ½ cup) for every 5 US gallons (19 L). In systems with heavy livestock, you can safely increase the initial dose by up to 10 times. For mature systems, use 2 oz (60 ml / ¼ cup) per 5 US gallons (19 L). This is a live product and should not be frozen.
